Patented Mar. 21, 1922.

Original application filed July 30, 1915, Serial No. 42,774. Renewed July 17, 1919, Serial No. 311,689.

Divided and. this application filed December 13, 1919.

T 0 all whom it may concern Be it known that i, JOHN D. Pnnnnsnn, a citizen of the United States, residing in Jackson, in the county of Lincoln and State of Wyoming, have invented certain newand useful Improvements in Firearms, of. which the following is a specification,

One object of my present improvements is to furnish an improved trigger-mechanism, or device, especially adapted for use in small arms, particularly in auto-loading pistols, in which the rearward end of the triggenbar has working movements in transverse directions. A. firearm of this class is described in my Patent No. 1,23%,733, dated August 3, 1920, granted on my 00- pending application (renewal) Serial No. 311,689, filed July 1?, 1919, in which also is described-but not specifically claimed the improvements which constitute the subjectmatter of the present application.

A further object is to provide a trigger mechanism or device in which the trigger is movable rearwardly to move the sear member, and is movable forwardly, and in which the trigger member by a second o1'-subse' quentfipull thereon to move it rearward,

after the first pull, cannot be brought into contact with the sear member tomove the sear member unless the trigger is irst permitted to move forwardly.

A further object is to provide a trigger mechanism or device having a trigger-bar or thrust member with a retractor-de'vice carried on and by such member, and so organized that the entire trigger mechanism or device may beremoved and replaced as a whole. Thus the trigger mechanism or device, although comprising several coactive parts, may be regarded a single member of the firearm.

' For convenience of illustration, the pres ent improvements are herein shown of the.

same construction, and as being applied to the same form and construction of firearm which is illustrated in said prior application; but it will be understood that said c0nstruction, and the manner of applying the device, may be varied within the scope and purview of the present invention.

Fig. 5 is fragmentary detail sectional view on substantially the same scale as Fig. 3, of a pistol provided withmy trigger mechanism or device, showing the trigger in rearward and downward position after pull on the trigger to move the sear member, the

trigger being moved to and held in such 'mechanism or device on the line 7-7 of imilar reference characters orv numerals refer to-similar parts throughout the several views. I

My trigger mechanism or device comprises, in its main elements or parts, the slidable member or controller N, the sear member S, and the trigger F, the magazine lock n, shown but not described herein, being described in detail, and the grip-safety device G, shown but not-described herein, being described in detail in my said patent.

The slidable member or controller N, only the lower portion thereof being shown for convenience, is located in the pistol rearwardly of the magazine recess or chamber M and forwardly of and adjacent to the sear member S, and is movable on the frame and grip-stock or handle portion of the pissurfaces 14 an upper surface 14: on each side of the slidable member or controller, one side. of the slidable member or con- -troller N not bein shown in the drawin s. D P; 1

but being in all respects similar to the side which is shown herein. The slidable-memher or controller N is extended below the shoulder- 14 and is provided with twin slots 10, a slot lObeing formed in each side of theslidable member or controller, have ing a downward face 14 and. an upward face let, the opposite slot 10 not being shown in the orawings but being in all respects similar to the slot which is shown therein. A longitudinal connection or portion 143 is formed by the slots 10 between the downward facesv 14 and the upward faces 14 The sear member S is pivotally supported on the gripstock or handle portion, the pistol and has at its upper end an arm i5 which is split or divided and forms twin arms to straddle. or pass on each side of the slidable member or controller "N vabove the shoulder 14 thereof, the opposite side of the-arm S not being shown in the drav ings but being in all respects similar to the side which is shown therein. Each twin arm S is provided with an end 17*, there thus being double or twin end 17, the .pur-' pose of the ends 1? being to engage or bear down upon the twin upper surfaces le of the shoulder 14." of the slidable' member or controller N. Each. of the twin ends 1'? has an end face 17, the end .faces 17 being shown partly in section in Fig.

The trigger F, which isprotected by a suitable guard, is mounted preferably in a slidable manner in the grip-stock or handle portion of the pistol, the front end of the trigger being located forward of the magazine recess orchamber The. trigger F comprises -a body portion or thrust-bar portion 11, which extends rearwardly into the slot 2 of the grip-stool: or handle portion of the pistol. The body portion or thrust bar portion 11 is slotted through as at 6 forming vside bars 6" 6" to provide the necessary space and clearance for the, cartridge receptacle or holder R which is received in the magazine recess or chamber M and is locked therein by the magazinelock m, the cartridge receptacle or holder passing between the side bars 6" 6", and limiting forward and rearward to its normal rearward and forward or longitudinal movements.

V The front end of the trigger F is provided with a finger-piece 6 which is slotted to receive the spring 6 and the plunger 6 The tr er-lever f is pivotally retained "DC in the finger-piece 6 by a pin 6 and is provided with an upwardly extending arm 12,, and a forwardly extending a-rn'i. 13. The arm-12' engagesv the shoulder 2 formed in the top wall of a vertical slot in the frame or receiver of the pistol, the shoulder 2" affording an abutment for the arm 12, and the arm 13 engages the plunger 6, the respective engagements'of the arms 12 and 13 with the shoulder 2" and with the plunger 6 actuated by the spring 6, tending to move the trigger F to forward or normal position. The connection of the spring 6 and the trigger-lever 7 holds the trigger, F bodily in its forward position, and also tends to hold the rear end of the trigger upward, the forward movement of the trigger F being limited by the curved ends of the side bars 6" (3" contacting with orstriking the curved ends of the cartridge receptacle or holder B. The rear end (3 of the trigger F is split or divided, Figs. 4 and 6, to provide twin ends to straddle or pass on each side of the longitudinal connection i l" of the slidable member or controller- N. e

Each of these twin ends comprises a recess 6 and an adjacent extended point or rear-face 6, the twin ends being received in the twin slots. 10 of the slidable member or controller N and being movable freely between the faces 14 and M thereof.

To assemble my trigger mechanism or device the trigger F may be introduced as a whole or entire part into the grip-stock or handle portionIof the pistol from the rear of the pistol through the slot 2", the various impeding or intervening parts not then being in place, and, before the trigger F is moved to its complete forward position, the top end lot the trigger-leverf may be revolved or turned tiorwardly and downwardl so as to be depressed below the top wall of said vertical slot in the frame or receiver of the pistol which receives the front. end of the trigger; The slidable member or controller N and the sear member S are then placed in their co-active relation to eachother and to the trigger F. The cartridge receptacle or holder R is inserted in themagazine re cess or chamber hi from the butt of the pistol andbetween the side bars 6 6 of the trigger F, the cartridge receptacle or holder being retained in place by the magazine lock m. The trigger F may be removed from the pistol as a whole or entire part in a similar way, except that in the course of removal the trigger is moved rearwardly instead of forwardly and in reverse manner, it also being understood that the cartridge receptacle or holder and the slidable member or controller and the sear member, andany other impeding or intervening parts of the pistol, are first withdrawn.

In operation: The slidable member or controller N is moved upwardly as described in my said patent, and the sear member S is moved to firing position as described in my said last mentioned co-pending application. By firing position here is meant the position of the sear member for locking the firing member or hammer H, of the pistol in position for movement to fired position or to discharge the firearm. The twin ends 17 of the arm S of thesear member are thus out of engagement with the twin upper surfaces 14 of the shoulder 14 of the slidable member or controller, and the trigger mem-' ber F is held in upward and forward position by the slidable member or controller, while the twin end-faces 17 of the sear member S are in position for engagement with the twin rear-faces 6 of thetrigger F, Fig. 3. Pull upon the fingei'epiece 6 of the trigger F moves the trigger rearwardly and the twin rear-faces 6 thereof into engagement with the twin end-faces 17 of the. sear member and moves the sear member to fired position or to position for releasing the firin member or hammer H of the pistol to fired position. As the sear member S is thus moved to fired position the twin ends 17 of the arm 8 thereof engage or bear down upon the twin upper surfaces 14 of the shoulder 14% of the slidable member or controller'and thereby move the slidable member or controller downwardly, which carries downwardly with it, and holds down, the rear end of the trigger F so that the twin recesses G of the rear end of the trigger are opposite the twin end-faces 17 of the sear member S, the effect being that the trigger F is then not engageable with the end faces 17 of the sear member by second or subsequent pull on the trigger F, 5, to move the sear member until the trigger F is Jl'St moved forwardly by the trigger-lever f, plunger 6 and spring 6 through release of pressure on the finger piece 6 of the trigger, and the rear end of the trigger is moved upwardly by upward movement of the slidable member or controller.
